Abstract

This research examined national elections' impact on crash risks of individual stocks listed in the Indonesia Stock Exchange. The study used national elections as a proxy for political uncertainty and negative skewness of stock returns as a proxy for crash risk. On the industry level, researchers found nuances in which national elections' impact varies according to industry, with some industries tending to have a greater risk of crash than others during national elections and post-national election periods.

Quantum Computing and Blockchain in Business

Arunkumar Krishnakumar

Fintech veteran and venture capitalist, Arunkumar Krishnakumar, cuts through the hype to bring us a first-hand look into how quantum computing and Blockchain together could redefine industries and life as we know it. Key Features Take a practical perspective on quantum computing and Blockchain technologies and their impacts on key industries Gain insights from experts who are applying quantum computing or Blockchain in their fields See where quantum computing and Blockchain are heading, and where the two may intersect Book Description Are quantum computing and Blockchain on a collision course or will they be the most important trends of this decade to disrupt industries and life as we know it? Fintech veteran and venture capitalist Arunkumar Krishnakumar cuts through the hype to bring us a first-hand look into how quantum computing and Blockchain together are redefining industries, including fintech, healthcare, and research. Through a series of interviews with domain experts, he also explores these technologies' potential to transform national and global governance and policies – from how elections are conducted and how smart cities can be designed and optimized for the environment, to what cyberwarfare enabled by quantum cryptography might look like. In doing so, he also highlights challenges that these technologies have to overcome to go mainstream. Quantum Computing and Blockchain in Business explores the potential changes that quantum computing and Blockchain might bring about in the real world. After expanding on the key concepts and techniques, such as applied cryptography, qubits, and digital annealing, that underpin quantum computing and Blockchain, the book dives into how major industries will be impacted by these technologies. Lastly, we consider how the two technologies may come together in a complimentary way. What you will learn Understand the fundamentals of quantum computing and Blockchain Gain insights from the experts who are using quantum computing and Blockchain Discover the implications of these technologies for governance and healthcare Learn how Blockchain and quantum computing may influence logistics and finance Understand how these technologies are impacting research in areas such as chemistry Find out how these technologies may help the environment and influence smart city development Understand the implications for cybersecurity as these technologies evolve Who this book is for This book is for tech enthusiasts – developers, architects, managers, consultants, and venture capitalists – working in or interested in the latest developments in quantum computing and blockchain. While the book introduces key ideas, terms, and techniques used in these technologies, the main goal of this book is to prime readers for the practical adoption and applications of these technologies across varies industries and walks of life.

Bridging Quantum Algorithms and Classical Finance: Portfolio Optimization Using QAOA and QUBO Framework

Arnav Aggarwal, Pranav Shrivastava, Rajneesh Kler +1 more

This study explores the integration of quantum computing techniques, specifically the Quantum Approximate Optimization Algorithm (QAOA), with classical portfolio optimization frameworks through the Quadratic Unconstrained Binary Optimization (QUBO) approach. Using monthly turnover data from the National Stock Exchange of India (NSE), this paper demonstrates the construction of a QUBO matrix by encoding expected returns and covariance-based risk profiles. Binary asset inclusion constraints are introduced into portfolios and then optimised using both brute force enumeration and quantum inspired solvers. The analysis reveals those combinations including Index Futures and Index Options exhibit superior risk-adjusted performance (Sharpe Ratio$\approx 0.286$). The hybrid approach suggests the promise of quantum inspired models as means to improve financial decision making under uncertainty. The results also give a robust template for scalable asset selection models that operate within the constraints of quantum computing infrastructure.

Risk estimation methodology in the post-quantum period

Maryna V. Yesina, Олександр Володимирович Потій, Yu.I. Gorbenko +1 more

The world is in the process of intensive creation and application of quantum technologies. On May 4, 2022, the President of the United States signed the «National Security Memorandum on Promoting United States Leadership in Quantum Computing While Mitigating Risks to Vulnerable Cryptographic Systems». Therefore, advancing leadership is an important challenge in quantum computing in general, while reducing risks to vulnerable cryptographic systems. Accordingly, standardized scientific and methodological support for risk assessment should be justified, accepted and applied at the international and national levels when quantum computing is used in general and especially when quantum computing is used in cryptology. The purpose of the work is to substantiate and develop a risk assessment methodology for quantum computing used in cryptology in the so-called “post-quantum period”. With this aim in view the following components were taken into account: the use of methods that have not yet arisen to combat cybersecurity threats; determination of the essence of the quantum risk assessment methodology; identification and documentation of information assets and their current cryptographic protection; research on the state of quantum computers and quantum-safe cryptography. Quantum risk assessment is considered, an ideal approach for identifying and prioritizing threats and vulnerabilities, as well as laying the foundation for the reliable and cost-effective development of systems so that they are resistant to quantum attacks. Quantum risk assessment provides organizations with the knowledge necessary to understand the extent of their quantum cyber risk and the terms in which quantum threats can arise. This will provide the organization with a basis for proactively addressing quantum risks, building a path to a quantum safe state, and implementing and validating quantum safe solutions.
